Theory of Thermodynamic Activity and Ionic Strength

The video tutorial explains the concepts of activity and ionic strength in chemistry. It begins with an introduction to these often misunderstood topics, followed by a detailed explanation of ionic compounds and the concept of shielding. The tutorial then discusses how ionic strength affects solutions and compares activity with concentration, highlighting the importance of using activity in non-ideal solutions. Finally, it covers how to calculate activity using activity coefficients, emphasizing the role of ionic strength and the use of tables for accurate calculations.
